I am making a retirement calculator. I am charting their assets vs expenses and showing how long their money will last. Say the person is 55 and they want to retire at age 65; this means that person has 10 more years of contributions (annual in this case) to put towards their retirement. I need to figure out how to show these additions for 10 years and then cut it off after that and start showing depreciation of assets. I need the chart data to automatically changed based on the input "Target retirement age" cell. Hopefully this makes sense. Thanks for any help!
